, Application filed May'7,

Be it known that Gnonen citizen of the United States, residing at 'useful Improvements in Attachments for.

Augusta, in the county of Richmond and State of Georgia, has inventednew and Slashers and Finishers, of which the-following is aspecification.

The object of the invention is to provide an attachment for the slasherand finisher commonly used in the textileart whereby the warp threadsmay be so operated upon that those lying in the 'selvage are ofi'set atspecified points, thus providing a gap in thewarp which will serve, inconjunction with a stopping device appliedto the loom,

to positively stop the latter. Warps runin the ordinary way will notaccomplish this result. The improved device herein shown and describedworks with the usual cut marker and each time a cut mark is made withdie in the usual way, the improved 'device operates upon the selva-gewarp threads to ofi'setthem. The use of the device relieves the operatorof the trouble of watching for out marks and in this way allows a tingreferred to.

one operator to increase the number of looms which he or she may run andthe operator can devote all his or her attention to the general stoppingcaused by the warp threads breaking.

Another objectof the invention is to pr0- vide means for the purposespecified whichis 811111319111 construction, durable and ef-;

fective in operation and inexpensive to manufacture and apply.-

Other objects appear in the following description'wherein the inventionis set forth in detail. The invention is illustrated and described in aspecific embodiment, to which,

however, it is not to be restricted. The

right is reserved to make such changes or alterations as the actualreduction to prac tice may suggest'insofar assuoh changes or alterationsarecompatible in spirit with the annexed claims.

Referring to the drawings, there is show'n' v in- Figs.-1iIand 2 aslashing and finishing machine which comprises theusual sizing apparatus1, theheated drum 2, the usual guide rolls 3, the leash-rods 4 and theremovable beam 5. This" apparatus just de scribed follows the ordinarywell-known construction, the warp being led from ape".

propriatebeams (not shown), thence to the SlZQebOX 1 thence lover heateddruin'2 and: around same to the uppermostfof the fguide rolls 3, soithat-it completely encireles the if drum, thence around theother guiderolls and around the Qleashrods toremovable beam-'5. The-warp threadsinthis'apparatus are of course separated between "the leashing meansand. the beam by an appro-' V priate combbut the latter-forms no partofthe present invention. Thepresent inven-I tion resides in means :foroffsetting the outermost warp threadson-one-edge, so jtha't a gap-ofspecified length 'will occur in the "selvage on one side. "For thepurpose or. 7

providing means for'automatica'lly stopping the loom when'this gapappears ,onthe latter, the gap is formed where the usualf-cut mark ismade with an appropriate marking apparatus or die and the improvedapparawe can be used with or without the die marking apparatus. Thereferred ."to

The guide rolls are of course put in'motion in the usual way and thatrolleron't'he extremeleft' hand end of the apparatus has attaohe'dto itsshaft a worm wheel 6 meshing with aworm 7 carriediby the shaft '8to 'iooi which power is transmitted byfappropriate 7 means (not shown) Thisshaft Bfisan; essential part of the us'ualform' of slasher and theimproved device is operated partly by this shaft and partly by'theshaft' 9 which is-also an essential' 'part of the usual form ofslasher; Shaft?) terminates adjacent the comb 10 and carrieson itsextremity agea-r 11, this gear meshing with-a gear 12 which is mountedonone' extremity of a a 60' diagrammatic view to illusshaft 13 journaledin appropriate bearing standards 14 carried by the frame of the slasher.I The'warp threads pass between the teeth of the comb 10.and over theroller 3 which carries the Worm gear 6 and the selvage warp threads areoperated upon by the improved devicebetweenthe comb and the roller 3this device operating at specified intervals indicating that a certainnumber of yards of warp have passed this point.

The warp threads having been treated in the size-box andpassed over theheating 1 drum 2, if the outside threads be pressed r in after suchoperation, the sizing will cause of an arm 19 which is slidingly carriedin V the legs of a U-shaped'member 20, the latter:

being carried by an appropriate bracket 21 by means of which itisseparated on the frame of the machine. v,

The U-shaped member 20'is disposed in Y I the direction of the width ofthe machine-- that is, in the direction of the length of the guide rollsand the combs-and it is provided with an upturned supporting arm 22 atwhose upper extremity a stud 23 is attached, the latter serving tosupport the double flanged pulley 24 whose axis is dis:

posed in the direction of the length of the '7 frame of the slasher-thatis, in the direc- 4 tion of the length of the shaft 8. The pulley 24 isdisposed between the-U-shaped member 20 and the arm' 23 and carries onthat side facing the U-shaped member an eccentrically disposed bossor'projection 25 1 a which is provided with a wrist pin 26 with lattershaft carries a double flange pulley. the latter,

which one end of a link 27 pivot'ally connects.

The pulley. 24 is rotated through the medium on the shaft 8 and to thatend the 28' over which a belt 29 is turned, being turned also over thepulley 24. Ohviously when the shaft 8turns rotary motion will beimparted tothe pulley 24 with, theresult that the link27 will bereciprocated and this link is designed to reciprocate the bar 19 atcertain specified intervals of time during the passage of the warpthreads from thecomb to the roller 3 f To this end there is mounted onthe arm 19 a bracket member 30 which is formed with an upturned ear 3lto which the remaining end 1 draw formed with the of, the link 27 ispivotally connected. This,

bracket 30 is formed with any extension 32 extending in the direction ofthe length of the arm 19 and toward the pulley 24, the

"bracket being provided with pairs of spaced lugs 33 and 34 whichstraddle the arm 19 on the upper edge. The bracket 30 is mounted so asto slide along the arm 19 as the pulley is provided a spring 35havingone'end con nectedto a laterally extending bracket36 formed with theU-shaped member 20. The other end of this spring connects at anintermediatepoint with a small red member 37 which is made preferably ofa single piece of vwire and formed with an eye 38 with which the end ofthe spring 35 con nects. One extremity of this rod member 37 ispivotally connected to the arm 19 at 39 but the other extremity of thisred member is free. Obviously thespring will serve to the lattercontacts with one leg of the U- shaped member 20 I moved against thetension of the spring to space the lug from the said leg and to forcethe roller 16 inward where it-will contact,

with the selvage thread of the warp.

Pivotally mounted on the arm 19 on one which is engaged by the free'e'ndof the rod member 37 to keep the nose of the pawl depressed, the tailand nose of the pawl. being on opposite sides of the pivot connection.

'The pawl is designed to be engaged on the nose by a lip 42 formed onthe extension 32 of the bracket 30 but this lip may only engage the pawlwhen the nose of the latter is raised and means'hereinafter described isprovided for raising the'nose. The lip 32, however, with the peripheryof the toothed disk 43, the latter beingrotatably mounted on a stud 44carried by U-shaped member20. This disk is provided on its one side witha plurality of axially disposed pins 46 designed to operatively engage alever 47 carried by a register or counter 48 whichis supported on abracket portion 49 also formed with the U-shaped member20. When the pawl41 has its nose out of engagement with the lip 42 of the extension 32 ofthe bracket 30, the bracket willonly slide backward and forward 19 asthe pulley 24 turns, the spring 35 0b and the arm will be is alwaysoperatively connected an upstanding support 45.

along the arm" the arm 19 inward until the lug 40 on V a side thereofthereis a pawl41 the tail of viously serving'to keep the armIQ-"inaposition whereits :lug. 410 "contacts with one leg of theU-shaped member. By'the provision of the free "extending en'd' of therod 7 37, :the' spring: also serves to. keep the pawl passed the roller16, however, the arm 19 is designed to be forcedin toward the Warp untilthe roller contacts with'the outermost warp threads 'and -forces'themin. toward adjacentthreads to provide the 'gap 15 pre viously referredto. To this end there is mounted :on the shaft'13 a cam "50 theperiphery of which follows the outlinelof a spiral, thus providing adirect dropffrom the highest pointto'the lowest point of the cam,"asindicated at 51 in Fig. 5. Playing on the periphery ofth'is cam'50 thereis the extremity of one arm of -a bell crank lever '52; Thislever ispivotally mountedpas at 53, ona bracket 54' formed with one of thebearing supportsl. "The extremity :of-the remaining arm of this lever'pivotall-y con} nects with one end of a bar 55, the other extremity ofthis bar passingslidablythrough a slot formed transversely through thearm 19. That end 'of'thebar 55 passing through the arm-19istapered ofi'as'indicated at 56 and this tapered end or-nose of the bar passes underthe nose end'of the pawl 41. Obviously as the shaft 13 turns the cam 50is turned with it and the bell crank lever 52. is rocked on its .pivot53 against the pressure of a spring 57 which is, attached on the bracket54 and bears against-thatarm of the lever 52 to which the bar '55 isconnected. The spring-serves to keep thebellcrank lever in contactwiththe periphery of the cam and thus provides for; the rocking of thelever during the movement "ofthe cam, this rocking of the lever, ofcourse, lmpartinga I'BCIPIOCELtIIig movement to the bar 55 causing thelatter tomove in and out through the slot formed in the arm '19; Whenthe bell crank lever is on-the highest point of thecam, 1 the bar- 55reache's""the limit of its movement through the arm 19- inthedirectionof the disk 43.- In such a position of the bar the under edgeof the pawl 41 adjacent the nose is engaged by the tapered end of thebar andraised so 'thlat the nose'reaches' a point where it mayfbeengaged by the lip 42 of the extensionof the bracket 30." When thebracket 'moves forward due tofthe turning of the pulley 24, it serves,"byengagement of the'lip 4:2 with the pawl-41, to carry the arm'1-9--forwardwvith it ag'ainst' the tension of the V againsttheadjacentl'threads, the sizing-0n adjacent threads causing'them toa'dhere'together andpro'duce the gaps 15. When the arm of the bellcrank] lever drops to the lowest "point on the cam 50 as indicated at51, the bar '55 is withdrawn from its former position and the pawl 41 ispermitted to assume its normal'position, the spring v35 V at this timedrawing the arm 19 backward and raising the tail and depressing the noseof'the pawl; The arm '1 9 thus remains inert until the cam 50 againeffects the operation ,of the 7 bar 55. jOb-viously tthe angular'velocity of the shaft-(=13 is low and its speed ratio with reference tothe speed ofthe shafts on other parts of the slasher is {such that thebar 55 is operated at the proper injtervals to raise the roller-16 toproduce the gaps 15 at the=desired pointson the warp.
